Quarry with extraction of building stone from huge blocks of porphyritic granite produced by landslides and rock fall. The granite is a typical variety within the Andalshatten Batholith. Granite from this site was extracted between 1993-1995, and has, for example, been used in the floor of the minicipality house in Vevelstad, at the Geological Survey of Norway, and for a war memorial in Mosjøen. The quarry is not in operation today, but is situated right beside the trail leading up to Oddvar I. N. Darren’s art installation “Opus for Heaven and Earth” (non-geological site O2-6), a large circle on the rock face where the granite has been polished.

The site is close to the trail to the art installation, and is visited by tourists. However, better information about the granite and the use of the stone as building material could be added.
